Light Travel Experiment Procedures

The video tutorial teaches how light travels through an experiment using index cards, clay, and a flashlight. Students prepare index cards by drawing lines and punching holes, then set them up in a straight line with clay. They shine a flashlight through the holes to hit a bullseye on the last card. The experiment is repeated with adjustments, and students complete a worksheet and diagram to reinforce learning.
